This sheet designed for the ottomon sleeper bed by #SpaceInnovations is very well thought out ! It goes right over the ottomon bed when pulled out and just slips over the top. Just add a pillow , a top sheet and a blanket and you're all set. When you're done using the bed just pull the ottomon sheet off and toss into your washer. No fuss to this one. It washes well and for the price you'll want to have at least one spare. I purchased this in the Gray and i'ts a gorgeous silver blue gray color. I'm extremely happy with my purchase.
